Olivier Dahan's 'La Vie en Rose' is a sweeping, nonlinear biopic of the French chanteuse Edith Piaf, powered by Marion Cotillard's astonishing, fully embodied performance charting the singer's rise from Parisian streets to global fame amid addiction and tragedy. The film leaps freely across her turbulent life, unified by Cotillard's transformation and Piaf's immortal songs. Uneven in structure but emotionally overwhelming, it earned Cotillard the Academy Award for Best Actress, the first ever for a French-language role, a landmark, career-defining triumph.
